A390 Phase U book 1current unbalance alarm.
(10)
Current Unbalance at It indicates a 20 % unbalance in the current
Phase U B1 distribution between this phase and the smallest
current of the same phase in other book, only when
the current in this phase is higher than 75 % of its
nominal value.
Quick Parameter Reference, Faults and Alarms
Description Possible Causes
High current at the inverter output (see figure 8.1 of the
CFW-11M user's manual).
Bad electric connection between the DC bus and the
power unit.
Bad electric connection between the power unit output
and the motor.
Note: In case of fast acceleration or braking, one of these
alarms may be indicated momentarily, disappearing after
3 seconds. This is not an indication of any anomaly in the
inverter.
If the alarm persists when the motor is operating at a constant
speed, it is an indication of an anomaly in the current
distribution among the power units.
